BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to compositions, kits and methods fortreating hair. More particularly, the present invention includescompositions, kits and methods for treating hair using compoundsdescribed below, but without agents for effecting polymerization.

The present invention also provides novel compositions that allow forlong-lasting moisture resistance, that are more repellant to dirtparticles than natural hair while simultaneously leaving much lessresidue and producing long-lasting shine.

Background of the Invention

The hair care industry is a multi-billion dollar industry in the UnitedStates alone. The industry includes the development, production, andmarketing of a large array of products for hair care, includingshampoos, gels, mousses, lotions, sprays, conditioners, coloringproducts, pomades, serums, waxes, and repair products. Most of theseproducts utilize pre-formed polymers developed to impart a desiredcharacteristic upon application to a user's hair. For example, polymersare used to give hair shine, style hair, preserve hair style, give haira desired texture or feel, enhance hair color, condition hair, dry hairso it sets quickly, straighten or smoothen hair, soften hair, strengthenhair, make hard-to-treat hair manageable, enhance optical properties,provide hold to hair, provide frizz control and/or to repair damagedhair.

Some of the above-identified beneficial attributes have been afforded inexisting hair care products through use of compositions containingconditioning agents such as silicones or other polymers, which have ahigh affinity for keratin and especially for scalp hair. Such compoundsinclude, but are not limited to silicones such as cyclomethicone,dimethiconol, dimethicone, cyclopentasiloxane, cyclomethicone,trimethylsiloxyphenyl, dimethiconol, cyclopentasiloxane dimethiconecopolyol. However, the coating on keratin fibers, such as the hair,obtained with such compositions often has an unpleasant tacky feel andalso may be readily lost via transfer, for example when a hand is passedthrough the hair. In addition, as a result of such transfer the hair maygive the impression of being dirty, sticky or tacky. Also, the effectsof the use of such silicone compounds and polymers is not long lastingas they are removed by shampooing the hair, thus making it necessary torepeat application of the compositions to the hair, for example, afterrinsing, washing or shampooing.

Attempts have been made to treat hair with certain acrylate monomers andpolymerize them in situ by free-radical polymerization. For example,U.S. Pat. No. 3,676,550 discloses use of certain acrylate andmethacrylate compositions as hair treatments. Those compositions employan “inert solvent” (which contains 10 to 90% water; the remainder beingwater-miscible organic solvent).

Unfortunately, compositions and methods that employ in situ free radicalpolymerization tend to degrade the hair, since harsh chemicals areinvolved. Another problem reported for such compositions and methods isthat the chemicals employed irritate and/or are harmful to the hairand/or skin and leave the hair feeling harsh, as well as causing hairdiscoloration. Furthermore, many such hair treatments may involvereduction of hair prior to treatment, which causes additional hairdamage.

One approach to avoid the harsh chemicals and/or conditions involved inin situ polymerization has been to avoid monomers that do not requiresuch initiators, but rather employ monomers that readily polymerize inthe presence of moisture (water). Accordingly, U.S. Pat. No. 5,082,010shows that cyanoacrylates have been used as a treatment for hair.Cyanoacrylate monomers readily polymerize in the presence of moistureand are said to be “instant adhesives.” “Crazy Glue” (2-cyano acrylate)is such an example. In addition, a medical glue, 2-octyl cyanoacrylate,is FDA approved for use as a wound adhesive for use in surgery. Contactwith the moisture in the air, or from a biological fluid or tissue, issufficient for polymerization of such cyanoacrylates.

Thus, existing hair care treatments suffer from numerous technicallimitations. In addition to these technical limitations, there arefunctional limitations and drawbacks of using existing hair careformulations. One problem common to many hair care products is poorefficacy and longevity. For example, existing hair care treatments arenot robust and can lose their efficacy over the course of a day. Manytreatments lose their efficacy upon exposure to water or excesshumidity. In addition, many hair treatments weigh down hair, flake off,leave unsightly residues, fail to dry and set quickly, do not provideadequate hold, and are not effective for hard-to-treat hair (e.g.,naturally curly hair). Treatments have been developed which overcomesome of these issues; however, they typically involve permanentlytreating the hair with reducing and/or oxidizing agents which can damagehair. Thus, there remains a need for hair treatments that withstand therigors of a typical user's daily routine and maintain efficacy in avariety of environments without damaging hair fibers. It is preferablethat a hair treatment be long lasting, not weigh down hair, not flake,and not leave any undesirable residues. Furthermore, the hair treatmentshould preferably dry and set relatively quickly, provide adequate hold,and be able to manage hard-to-treat hair.

SUMMARY OF THE INVENTION

Moisture Resistance

Moisture on hair and its penetration into the hair can disturb thearrangement of hair proteins, resulting in cosmetically undesiredchanges, such as, an increase of frizz. The present invention provideshair, in particular hair on or from the scalp, with beneficial moistureresistance properties. Moisture resistance in the present inventionrefers to the hysteresis of water sorption/desorption when measured byDynamic Vapor Sorption (DVS). In DVS a sample is placed on amicrobalance exposed to a continuous flow of air with predetermined andconstant relative humidity. As the humid air passes over the sample, azone of constant moisture concentration is created around it. This zoneallows the rapid establishment of water vapor sorption or desorptionequilibrium by maximizing mass transport of water vapor into and out ofthe sample.

Mass changes in the sample (e.g., a swatch of hair) due to water vaporsorption/desorption can be measured between different levels of relativehumidity at a particular temperature. The change in mass can be plottedas a function of the relative humidity, which provides information aboutthe nature of water vapor sorption phase (absorption and/or adsorption)when humidity is increased, or, conversely, the nature of desorption ofwater, when humidity is decreased. The difference in changes in mass atany particular value for relative humidity in the sorption anddesorption phases is known as the hysteresis and can be used as ameasure to evaluate the ability of a hair treatment to resist or controlmoisture on and in hair. As described below, the invention affordsreduced hysteresis especially over relative humidity values range of30-80% RH.

In the context of the present invention, moisture resistance is measuredaccording to DVS Protocol I. A “decrease in moisture flux” means thattreated hair exhibits a decrease in hysteresis when subjected to dynamicvapor sorption according to DVS Protocol I.

DVS Protocol I

1. 1.50 g of bleached hair tress (standard single bleached, wavy frizzyhair from International Hair Importers, White Plains N.Y., USA) isdampened with 0.30 mL de-ionized water, optionally via pipet, andlightly combed through to remove any tangles.

2. Apply composition to the hair tress according to the followingamounts: for a serum (0.09 g to 0.12 g), for a cream/lotion/mousse (0.20g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributedevenly and combed through the hair. Preferably the weight ratio offormulation to hair should be approximately 0.073 for serums, 0.15 for acream/lotion/mousse and 0.25 for a spray.3. Styling consists of 10 passes with a hair brush and blow drier set tohigh, approximately 50-120° C.4. After styling, the hair is cut and sections from the middle of eachtress (approximately 300 mg) are analyzed via DVS.5. DVS conditions are as follows. Unless otherwise stated thetemperature employed is 25° C. Sorption phase: Start at 30% RH andincrease up to 90% RH, each step increasing RH by 10%. Desorption phase:Start at 90% RH and decrease down to 0% RH, each step decreasing RH by10%. At each RH condition, the sample is maintained for 4 hours, and thestep up or down to the next RH level is programmed to occur over 20 minperiod.

Monitoring the hysteresis values from such a DVS experiment on hairsamples allows assessment of the ability of a hair treatment to resistor control moisture.

The present invention affords superior moisture resistance compared toeither (1) a control treatment using water and (2) a silicone product,such as Kérastase® Oleo Relax Serum (purchased in the USA, 2008;hereinafter “Commercial Example A”), which in fact increased thehysteresis compared to water. Preferably, use of the invention on a hairtress as described above affords a 4% reduction in the averagehysteresis values compared to control (water-treated) hair over therelative humidity range of 30-80% when examined by the DVS protocoldescribed above. More preferably, use of the invention on a hair tressas described above affords more than a 10% reduction and still morepreferably more than a 20% reduction, in the average hysteresis valuescompared to control (water treated) hair over the relative humidityrange of 30-80% when examined by the DVS protocol described above. Evenmore preferably, the invention affords a 50% or more, or even an 80% ormore, reduction in the average hysteresis values compared to control(water-treated) hair over the relative humidity values range of 30-80%RH when determined by the DVS protocol described above.

Weightlessness

Those who use hair care products desire the beneficial effects describedabove. However, such users do not want the feeling of residue/product inor on their hair. A composition that maintains performance, but whichdoes so with less residual weight or “feel” in the hair is, therefore,preferred.

The compositions of the present invention, while maintaining productperformance, beneficially lose no less than 25% of their weight,preferably 50% of their weight, more preferably no less than 70% oftheir weight, still more preferably no less than 80% weight, and stillmore preferably no less than 90%, and most preferably 95% or higher oftheir weight after heating at 55° C. and 10% RH for 10 minutes (forspray formulations) and 30 minutes (cream/lotion/serum/mousse)formulations according to the “Weightlessness Test I.”

Weightless Test I

Composition is dispensed into an uncovered container and spread outevenly. For instance, the container is a round container with a diameterof 9 cm and a lip measuring 0.5 cm.

1. The containers are labeled and then weighed immediately before andafter dosing with 3 g of formulation.

2. Compositions are left to equilibrate at ambient conditions (25° C.,30% RH) for 5 minutes before placing into the oven.

3. The container is placed into an oven controlled at 55° C. and 10% RH.

4. Each dish is removed and its mass recorded at 10 minutes for spraycompositions and 30 minutes for cream/lotion/serum/mousse compositions.

The compositions for treating hair according to the invention on averageleave at least 25% less residue upon dry-down when following packageinstructions for amounts used for Kérastase® Oleo Relax Serum(“Commercial Example A”), John Frieda® Frizz Ease (“Commercial ExampleB”), Biosilk® Silk Therapy (“Commercial Example H”), Redken® Smooth DownHeat Glide (“Commercial Example C”), Nexxus® Sleek Memory StraighteningSmooth Spray (“Commercial Example D”), Barex® Re-define Crème(“Commercial Example G”), Fekkai® Glossing Cream (“Commercial ExampleE”) and Bedhead® Curls Rock (“Commercial Example F”) (all purchased inthe USA; 2008). It is believed that one reason for the “weightlessness”benefits of the inventive formulations is that they do not require, andpreferably do not include, silicone compounds at levels found in theabove identified hair care products.

Dirt Resistance

Many materials are used to control or reduce moisture penetration intohair fibers. However, the majority of these materials are oil-based orsilicone-based. The resulting effect is modest moisture resistancecombined with a heavy residue feel which attracts grease andparticulates. It is desirable in the art to create a composition thatwill control or reduce moisture penetration into hair fibers whileleaving the hair feeling lightweight, non-greasy, and minimizingattraction of dirt/particulates.

The attraction of dirt and particles to the hair leaves the hair limper,heavier, and duller throughout the day. The ability to resistenvironmental pollutants gives the hair longer lasting style and shine.Accordingly, the ability of the present inventive hair care compositionsto resist dirt accumulation was examined and compared to CommercialExample A. Corn starch was selected as simulated dirt. USP corn starchis uniformly-white and can associate with hair, providing excellentcontrast on black hair, thereby allowing for a quantifiable Gray-scalemeasurement via digital photography. Remaining corn starch was alsoassayed by gravimetric analysis.

Starch Resistance (Gravimetric)

The inventive hair care compositions when tested on hair as describedbelow should afford gain in weight of no more than 15% by weight,preferably no more than 10% by weight, more preferably no more than 7%weight, and most preferably no more than 5% by weight when subjected toStarch Test I. As a measure of resisting dirt, “weight gain” refers tothe weight gain measured according to Starch Test I.

Starch Test I

1. 1.50 g of virgin dark brown hair tress (International Hair Importers,White Plains N.Y., USA) is dampened with 0.30 mL of water, optionallyvia pipette.

2. Apply composition to the hair tress according to the followingamounts: for a serum (0.10 g to 0.12 g), for a cream/lotion/mousse (0.20g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributedevenly and combed through the hair. Preferably the weight ratio offormulation to hair should be approximately 0.073 for serums, 0.15 for acream/lotion/mousse and 0.25 for a spray.3. The hair was styled with a hair brush and blow drier on high speedand high temperature, approximately at 50-120° C. for 30 seconds.4. The tress is saturated in a bath of corn starch, for instance, inabout 2 grams of corn starch, USP.5. The tress is removed from the corn starch bath and shaken by handuntil all loose corn starch is removed, for instance, for 10 seconds.6. The tress is weighed and the new mass is recorded.

The present invention may be used on any animal with hair. The system isparticularly useful for treating human hair. However, the hair or fur ofother mammals may also be treated. For example, the hair or fur ofdomesticated animals such as dogs and cats may be treated using theinventive system. In addition, the hair or fur of test animals such asrodents (e.g., mouse, rat, rabbit, guinea pig, etc.) or primates mayalso be treated. In certain embodiments, hair samples from a human(e.g., hair clippings) or other animals are tested with the presentinvention. Hair or fur samples treated with the present invention areconsidered to be within the scope of the invention. These hair or fursamples comprise compound on the hair or fur. In certain embodiments,the hair is human hair. In other embodiments, the hair is non-humanhair. In certain embodiments, the hair or fur is dog or cat hair or fur.In other embodiments, the hair is rat, mouse, guinea pig, rabbit,gerbil, or primate hair.

In this example, the measure of the hair's shine/luster is proposed.After applying a composition and curling and brushing a hair sample, thehair would be wound around a cylinder and placed under a lamp thatmimics sunlight. The width of the cone of luster will be measure andcompared with that of a commercial product.

In this example, the measure of the hair's break strength is proposed.Single hair fibers (treated and untreated) can be attached to an Instronwhich will pull at one end of the fiber, breaking the fiber at a certainforce.

In this example, the measure of the hair fiber thickness is proposed.Cross sections of hair fibers (treated and untreated) can be examinedand measured by microscopy.

In this example, the humidity resistance of the treated hair isproposed. This property can be measured by placing the styled hair tressin an atmosphere of high humidity.

In this example, the feel is proposed. The parameters of feel can beassessed for a given material on the hair fiber. Several parameters suchas tack, slip, stiffness, smoothness, grease, and strength can beevaluated by a blind test of experts.

Example 18—Non-Alcohol Aqueous Styling Spray Gel

The fluorinated compound was first preblended with a non-ionicemulsifier. Preblending of the emulsifier and fluorinated compoundensures proper formation of the suspended emulsion droplets resulting ina single or multi bi-layer coating of the fluorinated compound. Theconcentration of emulsifier remained under the CMC (critical micelleconcentration) as micelle formation does not improve the stability ofthe suspension. The composition was homogenized such that the dropletsize was less than 15 microns. This allows for lower oil to emulsifierratio, proper dispersion of the suspended droplets and stability of thecomposition. The result was an aqueous based suspension of coatedfluorinated compound, which resists coalescence, flocculation, and/orphase separation of the fluorinated compound. Applying shear to thecompositor (e.g. spray pump), reduces the viscosity and allows fordelivery of the fluorinated compound via a uniform spray pattern.Removal of the shear, allows the viscosity to recover and thecomposition to stabilize.

Comparative Example 1—Moisture Resistance

The humidity resistance of hair swatch treated with a preferredembodiment of the present invention (Hair Spray A) was compared to thatof hair swatch treated with a competitor product (Commercial Example A)as well as with untreated hair swatch using the Dynamic Vapor Sorption(DVS) Protocol I, discussed above. The amounts of products applied(scaled based on package instructions) are shown in Table 1. Targetamount of product is as follows: 100 mg (Commercial Example A), and 370mg (Hair Spray A).

TABLE 1 Overview of samples analyzed by DVS. Amounts were scaled downfrom package instructions.

As discussed under “Moisture Resistance” above, differences in wateradsorption/desorption at a particular relative humidity (the“hysteresis”) can be used as a measure to evaluate the ability of a hairtreatment to resist or control moisture on and in the hair. In FIG. 1,the lower overall hysteresis values for the Hair Spray A treated samplesindicate that less water was able to adsorb onto and penetrate into thehair that for the Commercial Example A-treated samples. This is in linewith the hypothesis that the invention creates a vapor barrier on thehair fiber. On the other hand, the Commercial Example A-treated samplesbehave very similarly to the water-treated samples demonstrating poorvapor barrier function. In fact, the 5 treatment Commercial Example Asample with multiple shampoos performed worse than the water treatedsample. This is may be a result of the shampooing increasing the hair'sporosity and the inability of Commercial Example A treatment to providean adequate barrier to protect the hair fibers. As seen in FIG. 1,multiple applications of Hair Spray A increased moisture resistancewhile the silicone-based Commercial Example A did not demonstrate anyresistance versus the water-treated sample at 60% and 80% relativehumidity.
